29th & Grove Groundwater Cleanup Moves Forward: What Wichita Residents Should Know Before Sept. 12
The Kansas Department of Health and Environment (KDHE) has approved the engineering design for the groundwater cleanup systems at Wichita's 29th and Grove Site. That approval moves the project from planning toward construction — and gives residents an important opportunity to understand what is coming next before work begins.
Public Availability Session: Sept. 12
KDHE and Union Pacific Railroad representatives will hold an open-house-style public availability session on Saturday, Sept. 12, 2026, from 1–4 p.m. at Brewer Community Center, Multipurpose Room 114, 1329 E. 16th St. N., Wichita, KS 67214.
Residents will be able to review information about the planned groundwater cleanup system, ask questions directly, and learn whether their property may fall within areas targeted for vapor-intrusion evaluation or other testing.
What changed
KDHE approved Union Pacific's engineering design drawings for the groundwater cleanup systems on July 30, 2026. The approved design includes planned extraction and injection wells, treatment buildings, and underground pipelines used to move groundwater through the cleanup system.
Approval of the design does not mean construction is already complete or that cleanup is finished. Union Pacific still must bid the construction work, select a contractor, obtain necessary construction-related approvals and materials, and secure required discharge permits before treated groundwater can be discharged to Chisholm Creek. KDHE has said those NPDES permit applications are under review.
What residents should know about the contamination
The primary contaminant associated with the site is trichloroethylene (TCE), an industrial solvent.
KDHE describes the groundwater plume as extending roughly 2.9 miles from the site area.
KDHE states that Wichita's public water system is not impacted by the TCE plume and remains safe for drinking and bathing.
Vapor intrusion remains an important property-level question. KDHE is reviewing a draft vapor-intrusion re-evaluation report, and residents can ask whether their property is within the zone targeted for indoor-air testing.
Union Pacific is responsible for the cleanup work and associated cleanup costs according to KDHE.
Why the Sept. 12 session matters
This meeting is most useful if residents arrive with property-specific questions. Bring your address and ask representatives to show you exactly where your home, business, church, school, rental property, or other location sits in relation to the groundwater plume, vapor-testing area, proposed wells, pipelines, treatment buildings, and construction zones.
Questions worth bringing
Is my address inside the groundwater plume or the vapor-intrusion evaluation area?
Has my property been tested, should it be tested, and what testing remains outstanding?
Where will extraction wells, injection wells, pipelines, and treatment buildings be located near my property?
What construction impacts should residents expect — traffic, noise, access, excavation, road closures, or other disruptions?
What cleanup standards will determine whether the project is working, and how often will results be reported publicly?
What is the projected construction and cleanup timeline, and which milestones should residents watch?
How will vapor-intrusion findings be communicated to property owners, tenants, schools, churches, and businesses?
What happens if monitoring shows contamination outside the currently identified boundaries?
The RRCBA connection
For RRCBA, this issue sits at the intersection of several Community Standards: health, neighborhood safety and quality of life, communication, civic engagement, housing, and equitable neighborhood investment. Environmental cleanup is not only a technical engineering project; it also affects whether residents have timely information, meaningful participation, property-level clarity, and confidence that long-term decisions are being monitored in the public interest.
The goal is not alarm. It is informed participation. Residents should understand the science, see the maps, know the timeline, ask property-specific questions, and have a clear way to stay involved after the open house.
Official resources
KDHE maintains the official 29th and Grove project page with public-meeting information, cleanup documents, implementation updates, maps, reports, and frequently asked questions. Project materials are also available at the Maya Angelou Northeast Branch Library, 3051 E. 21st St. N., Wichita. KDHE's project contact number is 785-296-8896.
Stay involved beyond the meeting
Attend the Sept. 12 session, bring your address, take notes, and share what you learn with neighbors who may not be able to attend. Then continue the conversation through RRCBA's committee structure so health, neighborhood safety, communications, civic engagement, housing, and other connected priorities can be tracked together rather than in isolation.
Better information leads to better questions. Better questions create stronger accountability. And stronger accountability gives residents a better chance to shape what happens in their own neighborhoods.
